2024-02-20arm64: config: disable new platforms in virt.configArnd Bergmann
A couple of new platforms got added since last year when Mark added virt.config, so turn these off as well. Link: https://lore.kernel.org/r/20240219093819.644324-1-arnd@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2023-09-04kbuild: Show marked Kconfig fragments in "help"Kees Cook
Currently the Kconfig fragments in kernel/configs and arch/*/configs that aren't used internally aren't discoverable through "make help", which consists of hard-coded lists of config fragments. Instead, list all the fragment targets that have a "# Help: " comment prefix so the targets can be generated dynamically. Add logic to the Makefile to search for and display the fragment and comment. Add comments to fragments that are intended to be direct targets.

2023-03-17arm64: virtconfig: Further shrink the configMark Brown
After disabling platform support there's still some more pruning we can do to the virtconfig size, there are a number of drivers and subsystems which are not likely to be useful on mach-virt and so can be disabled in order to further improve build times. Let's do so, noting that having PCI device assignment means that PCI devices might potentially appear. This is just an initial manual passthrough, there will be further savings available especially if we take a much more focused approach.

2023-02-13arm64: configs: Add virtconfigMark Brown
Provide a slimline configuration intended to be booted on virtual machines, with the goal of providing a light configuration which will boot on and enable features available in mach-virt. This is defined in terms of the standard defconfig, with an additional virt.config fragment which disables options unneeded in a virtual configuration. As a first step we just disable all the ARCH_ configuration options, disabling the build of all the SoC specific drivers. This results in a kernel that builds about 25% faster in my testing, if this approach works for people we can add further options.
